Adding the ability to invert some devices for de-embeding.

version 4.2.1:
Fixed problem with Windows 7 install.  Added balanced four-port de-embedding.

version 4.2.2:
Fixed bug, if Touchstone file did not exist, failed without warning.

version 4.2.3: (10 Nov 2011)
Improved Plot routine, not can specify normalization for Smith Charts and text for legends.

version 4.2.4:
CPW with ground plane backing models; fixed some Mason Plot issues.

version 4.2.5:
Fixed figuring how to detect missing files in the simulation (I hope)

version 4.2.5b:
Added model of flat_wire_inductor.xml in TinyCAD mason_lumped_elements

version 4.2.6:
Fixed bugs in some models.

version 4.3:
Major upgrade to PrimCalc- added the ability to view descriptions of the model directly in PrimCalc.  Where needed, added synthesis parameters to models so they run in PrimCalc.  Initially describe microstrip, stripline, and lumped element models, will add coplanar and possibly some miscellaneous others in 4.3.1 soon.

version 4.3.1:
Updated models, made improvements to the look of PrimCalc's description.

version 4.4:
Major upgrade to TinyCAD- can now left click in the "Tool Option" text and the cursor will appear in about the right place.  Need to fix a logical unit to pixel mapping problem to improve the mapping of click and cursor.  Also, added a button in the TinyCAD "Tool Option", so one can now launch PrimCalc and load the appropriate primitive model.  This does not fill in the appropriate values, just simplifies launching PrimCalc. Version 4.4.1 will probably fix the logical/ pixel mapping.

version 4.4.1:
Minor tweak on version 4.4, think I fixed the mapping of clicking to the right place in the text box.  Can now delete Arguments even if they were originally came with the part - to make dealing with optimization, variable, and calculation blocks easier to deal with.  Value column defaults to more reasonable value. 

version 4.4.2:
Minor tweak on version 4.4.1, can now use CTRL+SHIFT+F to perform a search on text in the design file.  CTRL+F still is flip- I never use flip, but am keeping it for historical compatibility.

version 4.4.3:
Can now add new arguments anywhere in the "Tool Option" list box, not just at the end.  Click a location and click "add" and a new argument row will be added.  Ports will be mapped correctly based on defined number, and not by order added in the design.  Multiple calculation blocks can now be used.  Fixed a "bug" in genetic algorithm where the best solution can be mutated to be bad, losing the best solution.  Added a warning so if a component is turned off (refdes set to no show) Mason reminds you.

version 4.4.3:
Fixed how TinyCAD add elements in the middle of the Tool Options.  TinyCAD's Generating Symbol References defaults to All Sheets now.  Ports and calculation blocks should parse according to the number, not the order added.  TinyCAD tool option display rearranges items when something is added or deleted.  Fixed some optimizer issues which could cause the best answer to be lost when dealing with highly non-linear figures of merit.  Mason now checks for duplicate parts in the design file (same ref des) and throws a warning.  When a dynamic component fails an assumption the actual calculated value is displayed.  Prevent Figures of Merit from reporting NaN (and other out of range issues).

version 4.4.4:
The Primcalc button in TinyCAD now launches a generic Primcalc window if the Tool Option is not referring to an actual primitive.  I think I'm handling "bad" arguments in Variable, Calculation, and Optimization blocks.  "Bad" arguments are most likely caused when the user adds an argument and leaves it undefined.  Now reports when variables report as NaN. 

version 4.4.5:
Better handling of comments in variable and calculation blocks. 

version 4.4.6:
Trying to save during optimization more.  Can embed units after calculations as follows:
Argument | W3 = W1 ; unit: mil ; this is an invisible comment

version 4.4.7:
Changed how the optimizer outputs figures of merits- added more details.

version 4.4.8:
Improved how the optimizer outputs figures of merits- added more details.  Improved the opt_output function (output the Touchstone file / update the plot / output the latest best circuit to TinyCAD schematic).

version 4.5:
Fixed bug for Prim2Pads- sometimes combined ASCII reported too many ports, corrupted the file.
Added PADS-INDIVIDUAL flag (only output PCB files with each individual component)
Added PADS-COMBINED flag (only output PCB file with components combined to one decal)
Added FIRST_POST flag (control which component the decal starts layout with)
Added mradialstub
Added bessel functions to the math parser
Added units to built-in contants
Subcircuits can now output to PADS ASCII files, other improvements
Mason Plot has Y-Labels, other features

  2. when performing an Update and Save (using the Mason toolbar), the Save will create a back-up of the old file.
